Fronius Symo 3.7-3-M Inverter

Fronius Symo 3.7-3-M – this is an independent review for Fronius Symo 3.7-3-M we have compiled for your reference. Feel free to add your comments or experiences at the bottom of the page.

Maximum flexibility for the applications of tomorrow.
Boasting power categories ranging from 3.0 to 20.0 kW, the transformer less Fronius Symo is the three-phase inverter for systems of every size. The high system voltage, wide input voltage range and two MPP trackers ensure maximum flexibility in system design. The standard interface to the internet via WLAN or Ethernet and the ease of integration of third-party components make the Fronius Symo one of the most communicative inverters on the market.

NB: The Symo Light does not include a Data manager Card as standard, you will need a Fronius Data manager Card if you want to wirelessly connect the inverter to the web.

Technology

 Unique Fronius PC board replacement process

The foundation of the unique PC board replacement process is laid as we develop our inverters, as PC boards can only be replaced if the device has been designed accordingly. This enables our Fronius Service Partners to provide the fastest inverter servicing on the market.

  Snap Inverter mounting system

The special feature in the design of our devices is that the connection compartment is separate from the power stage set compartment. They are installed separately. The connection area and all its cabling is fitted to the wall first. The power stage set compartment is fitted afterwards. The innovative Snap Inverter mounting system makes installation and servicing extremely user-friendly. The inverter is simply placed in the wall bracket and then secured. It is not necessary to remove the entire inverter for servicing, just the power stage set compartment. All the cabling, settings and configurations remain in place.

  Automatic HF transformer switchover

Fronius transformer inverters use a high-frequency (HF) transformer. The automatic transformer switchover facility produces three efficiency peaks. The result: a constant level of efficiency across the entire input voltage range, resulting in higher yields. Other advantages of HF transformer technology are the compact, lightweight design and safety as a result of the electrical isolation.

  Integrated WLAN interface

Simple, user-friendly system monitoring is very important to Fronius. With the Fronius Data manager, we are the first inverter manufacturer to offer a WLAN interface in the inverter itself. The inverter is connected to the internet without additional cabling and grants you the perfect overview of how the PV system is operating.

  Smart Grid Ready

Fronius inverters are ready for the Smart Grid of tomorrow. The inverters are optimally equipped to meet the technical requirements of grids in the future. A series of smart functions, known as Advanced Grid Features, are built into the devices. These include a number of control functions for optimum feed-in of reactive power and effective power. These functions are designed to enable stable grid operation even when the PV system density is very high and to prevent unwanted interruptions to feed-in and associated yield losses. Fronius inverters therefore help to guarantee the yield of a PV system.
